FWIW, I used an (unmodified, not automated) old air popper to roast coffee for
years - it works well! It's not precise at all, and you have to do it outside
because the oil + chaff get everywhere, but was a fun hobby.

Craig, there is nothing vintage in there -- that IS today's components.
What's probably throwing you is that you're seeing a European hot-air popper.
American poppers are closer to this:
https://www.amazon.com/Presto-04863-Poplite-Popper-Color/dp/B01G7DM3G2 and
don't have near the same number of controlled components or the interface.
That doesn't mean you can't hack it up and make something work. Why don't
you take a trip to the Scrap Exchange in Durham (http://scrapexchange.org/);
they may even have some hot-air poppers. You can also check out other thrift
stores in the area and see their appliances. A $5 popper is certainly worth
experimenting on.

How would you do it with today's components?
Thanks
